OIL-WELL EQUIPMEND 3 Application filed January 29, 1923. seriaim siasea,

To all whom it may concern:

- Be it known that I, ALBERT T. HAGAMAN, a citizen of the United States, and resident of Louisa, in the county of Lawrence and State of Kentucky, have invented certain Briefly stated an important-object of this invention is to provide a pumping means for wells having a supplemental or reserve traveling valve which is normally located in the lower portion of the working barrel and which is brought into play in the active portion of the working barrel when themain traveling valve becomes worn and unsafe for eflicient pumping.

A further object is to provide a pumping apparatus for wells wherein the upper or main traveling valve constitutes a sand arrester or collector, when thesupplemental or reserve traveling valve is brought into use and by reason of this construction the supplemental or reserve valve is maintained more or less free from the cutting action of sand suspended in the oil.

A further object is to provide a pumping equipmentwhereinupper and lower traveling valves are provided with separate spherical valves, each one of which is provided with a seat and by providing a plurality of valves at spaced points in the line the positive lifting of the oil is provided for.

A further object is to provide an oil well equipment of thecharacter specifiedv which is of highly simplified construction, durable in use and cheap to manufacture.

:Other objects and advantages will be apparent during the course of the following description. i

In the accompanying drawing, forming a part of thisapplication and in which like numerals are employed to designate like parts throughout the same, I

Figure 1 is a vertical sectional view through a working barrel equipped with the cooperating traveling valve, the upper valve being shown in the active part of theworkingbarrel and the lower valve being shown in the lower portion of the working barrel,

the lower portion of the working barrel be ing increased slightly in internal. diameter.

7 through the working rocated in the active portion 7 of the Figure 2 is a vertical sectional view 7 barrel equipped with travelling valves, the being arranged in its the upper and lower lower travelling valve operative position in-the active portion of barrel andthe upper travelling the working valve being positioned to prevent settling of the sand on the lowereworking barrel, the view also illustrating the separate and independent ballvalves for the several travelling valves. a 1 y In the drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a casing within which a pumping barrel generally designated by the numeral 6 is located and by'refer'ence to Figures 1 and 2 it will be seen that the working barrel consists of an active portion 7 within which, one of the travelling valves operates and the lower portionof the working barrel'is enlarged in internal diameter. As is well known the lower portion of the working barrel 6 is provided with a standing valve, the lower portion-of which is perforated for the admission of oil. 7

' ThGOll is elevated in the working barrel by means of a travelling valve 10 consisting of a purality of cup leathers 11 spaced by meansof the usual bushings and the upper portion of vided with a cage 12 within which a one-way valve 14 of spherical formation is located. The travelling valve 10, is of course, recipworking-barrel by an operating device, such asa pumping power connected to a sucker rod 15. Whenthe sucker rod 15 and the travelling valve 10 is moved downwardly in the working barrel the oil which has been previously elevated is passed through the travelling valve and the ball valve 14: is elevated.

On the subsequent upward movement of the travelling valve the oil is moved upwardly and outof the well to a suitable point of discharge such as a tank.

In the pumpingequipment now in use and in fact in connection with this invention the travelling valve 10 and more specifically the cup leathers 11 wear so that the working fit between the travelling valve and the working barrel is broken. In this case the travelling valve will} not pump efficiently and consequently will elevate the travelling valve 10 andbring a second travelling valve the travelling valve 10 is pro- 1 18 into the reducedportion? of-theworking pum 7 lower travelhng valve 18 1s 1n the enlarged portion 8 of the workingbaiirelit will be out of working enga ement with the wall of the working barrel. However, the ballvalve 20 in the lower travelling valve is intended to operate at both "positions of'the travelling valve 18.

The lower travelling valve is providedwith a one-wayspherical valve 20 bynieans of which the return o1 theoilisprevented. On the downward mo'vemcntot the travelling valve 18 when the sameis ts activeposition, the valve QOis eletated ahdthe oil will flow through the travelling valve -18 and atubeQQ, the said tube servi-i g torig'idly connect the upper and' lower valves. ff-lit will be seen that the lo wer jpjortion of the connecting and oil 'conducti tubefZB is proided with a seriesotimvardly projecting lugs or retaining devices'23 b'ymeans of which the upward n'io'vement ot'the valve 20 islimited. However; thednwardly projecting lugs 231110 not in any way i'nte'rterewith the passage of oil through tlli "tubeQQQ In operation the sucker rod 15' is reciprocated and the upperftravell i'ng valvfe' flO is arranged in th'eactivep ortion the work;- ing barrel while tl1elowerftravelli ng valve is arranged in the inactive iiortioni't ot the working barrel. When the cup 'leathei's 11 :become worn as a result "of sand suspended in the oil the well will not operate. efliciently and it is then that theilowe'r travelling valve 18 is brought into operation hyelevating the sucker rod 15. r

VVjhen the lower travelling valve 18 is brought into use the cupfleathersll which arenot worn constitute sand arrestersand therefore prevent the'sand suspended in the oil from settling on the cup leathersotthe lower travelling valve. It might be stated that it is only the uppercup leathersf 11ot the upper travelling valve whic'l wear and the lower cup leathers 11"of the "uppertrav- "elling valve then prevent thes'ettling "of the sandon the cup'leathers' o't'the low'er travelling valve. I v

On the downward movemen of the sucker rod 22 the oil is passed through the tr'avelling valve 18 and into the connecting tube 22 and on the subsequentupwardmovement of the suckerrod the oil ise'levated. Of course, thatpil contained in the ti'ibe22 passes upwardly through the working harr'el 10 and the valve cage 12 and then up wardlythrough the tubing. 'It will'be seen that the ball valves 14 and 20f'coact to prevent the' returhbf the oil which has been pumped and therefore should one of the valves be rendered inactive for any reason the other valve will continue to function thereby venabling the well to continue to produce,

\Vithrreference to the toregoing'description taken in connection with the accompanying drawing :it will be seen that the upper travelling valve 10 not only forms a means for pumping tutes a sand arrester by ineansot which the said is prevented from settling on the cup leathers of the lower travelling 'val've and by the oil but also consti-- reason of this construction the lite of the lower travelling valve is greatly prolonged and the necessity of "frequently pullingthe travelling valve is overcome. I

- Inrsummarizing it will be seen that the upper'or main travelling valve is originally arranged in the active portion of the'working barrel and when the same becomes worn the lower or supplemental working or travelling valve is elevated into the active portion of the working barrel. When the' supplemental working or travelling valve is elevated'to'its operative positionthe main travelling valve willact as'an arrester by means of whichthe sand is prevented-from collecting on the supplemental travelling W valve:

Itis to be understood that the form ot'the invention herewith shown and described is to be taken as a pre ferred example otthe same and what such minor changes in arrangem'ent and construction of parts maybe made as will remain within the spirit of the invention and the scope of what is claimed.

Having thus described the invention, what is claimed is:- a

1. An oil well equipment comprising a working barrel having active and inactive portions, main and supplemental travelling valves arranged in the working barrel, the main travelling valve constituting a sand arrester by means of which sand is prevented from settling on the supplemental valve.
